Daniel Rutherford’s current work focuses on public policies to reduce greenhouse gas emissions from the aviation sector and to control emissions from new and in-use heavy-duty vehicles. As the ICCT’s Aviation Program lead he serves as a technical observer to the International Civil Aviation Organization (ICAO) working group on aircraft emissions and technology. Prior to joining the ICCT, Dr. Rutherford completed a dissertation assessing the Tokyo Metropolitan Government’s diesel emissions policy, which established the world’s largest market for clean diesel technologies when implemented in 2003. He holds a B.A. in Chemistry from the University of Minnesota at Morris and a M.S. and Ph.D. in Environmental Engineering and Science from Stanford University.
